You can try it and see how smart the authors were (on this point).

You don't need to fire up -ds- beforehand. This can thus be
reduced to
local i = 1
foreach var of var * {
ren `var' var`i'
local ++i

In fact you don't need a loop. With -renvars- from the Stata Journal
(-search renvars- for location) you can go
renvars \ var1-var`c(k)'
What if var5 already exists (and it is 10th in order). Will -renvars-
be intelligent enough to sense it and adjust numbering accordingly? or
will it just crash with error 110 after renaming the fifth variable?
c(k) is held by Stata as the number of variables -- see results of
-creturn li- and it has a local macro persona `c(k)'.
Naturally -renvars- is doing the loop on your behalf. It also checks
for
name problems.
If Mai does not want all variables renamed, then the advice is
modified
accordingly.

How can I loop over vars to rename them by their order number.
so they become var1, var2, var3...?
